Description

Farsince 200G QSFP56 AOC integrates two QSFP56 SR4 optical ends with a factory‑terminated multimode fiber assembly to create a direct 200‑Gb/s connection between switches, servers or storage. The link runs four 50‑Gb/s PAM4 lanes at 850 nm to deliver full‑rate 200GbE for top‑of‑rack, leaf–spine and HPC cluster interconnects. Standard lengths from 1 to 50 meters cover short‑reach deployments.

The lightweight optical construction reduces bundle size and avoids EMI issues found in copper DACs, while hot‑swap QSFP56 connectors with pull‑tabs simplify service in dense chassis. Operation is from a 3.3 V supply with total power below 4.5 W per cable. Management and diagnostics follow CMIS 5.0 over I2C with SFF‑8636–style monitoring for temperature and optical power. Farsince supports project customization for length, labeling/serialization and deployment kits to streamline data‑center rollouts and upgrades.
